Abstract
This paper presents an integrated adaptive control of attitude and momentum for space station under parametric uncertainties and disturbances. Two loop control strategy is proposed having attitude control as outer loop and momentum management as inner loop in order to overcome the problem of different bandwidths. The control architecture is based on the theory of simple adaptive control which depends on model reference adaptive control (MRAC). Stability analysis is performed using Lyapunov’s direct method. Simulation results demonstrate the efficiency of the proposed control strategy over a linear controller in terms of robustness, tracking and momentum management. It also shows the advantage of introducing a dead zone in the momentum management loop in the proposed controller.
